Title: Picture forming device
Inventor: ADACHI HIROYUKI
IPC: B65H41/00
Filed: 1988-12-12
Abstract: PURPOSE:To stably separate film and a recording material all the time by providing a separating roller of a prescribed diameter so that the fixing film can be removed more easily from the recording material after the film passes through a press-contact part. CONSTITUTION:The separating roller 27 is provided to deviate a traveling direction to a direction away from the recording material surface on which a toner picture is fixed after the fixing film 24 passes through a nip part N. The diameter of the separating roller 27 is 16mm or below, preferably 12mm or below, and the outer periphery of the roller is coated in a prescribed manner. When the fixing film 24 comes to the position of the separating roller 27, it is deviated to a direction away from the toner sheet surface because of curvature. Until the fixing roller reaches the deviation point, toner on the recording material is sufficiently cooled and solidified. Since the firmly fixing force between the toner and the sheet is sufficiently great, the film 24 never develops offset to stably separate them.
